Answer:
Option A is correct.
The given expression :
then;
![a^2 = 36](https://tex.z-dn.net/?f=a%5E2%20%3D%2036)
Step-by-step explanation:
Given the expression: ![\frac{a}{4} = \frac{9}{a}](https://tex.z-dn.net/?f=%5Cfrac%7Ba%7D%7B4%7D%20%3D%20%5Cfrac%7B9%7D%7Ba%7D)
Cross multiplication the given expression following steps are as follow;
- Multiply numerator of the left-hand fraction by the denominator of the right-hand fraction
- Also, Multiply numerator of the right-hand fraction by the denominator of the left-hand fraction.
- then, set the two products equal to each other.
Using cross multiplication, on the given expression;
![\frac{a}{4} = \frac{9}{a}](https://tex.z-dn.net/?f=%5Cfrac%7Ba%7D%7B4%7D%20%3D%20%5Cfrac%7B9%7D%7Ba%7D)
First multiply the numerator of the left hand fraction(i.e,a ) by the denominator of the right hand fraction (i,e a)
we have;
![\frac{a \times a}{4} = 9](https://tex.z-dn.net/?f=%5Cfrac%7Ba%20%5Ctimes%20a%7D%7B4%7D%20%3D%209)
Simplify:
[1]
now, multiply numerator of the right-hand fraction( i.e, 9) by the denominator of the left-hand fraction (i.e, 4 ) in [1]
we have;
![a^2 = 9\times 4](https://tex.z-dn.net/?f=a%5E2%20%3D%209%5Ctimes%204)
Simplify:
![a^2 = 36](https://tex.z-dn.net/?f=a%5E2%20%3D%2036)
Therefore, the given expression is equal to: ![a^2 = 36](https://tex.z-dn.net/?f=a%5E2%20%3D%2036)
